Talk:2286: 6-Foot Zone

Ok... 34 feet, in total, but how many hands? (All of which you should wash!) 162.158.34.210 23:34, 27 March 2020 (UTC)

Love it. Given the extra 1.7 feet for the person, a radius of 20.53 hands. If it were just 6 feet, 18 hands -- brad --108.162.216.122 00:55, 28 March 2020 (UTC)

So Randall is figuring about 1.7 feet diameter for the person. --172.68.174.70 00:40, 28 March 2020 (UTC)

The 190,000 people / mile^2 assumes (I'm guessing) flat ground. Skyscrapers make a difference [citation needed] -- brad --108.162.216.122 00:55, 28 March 2020 (UTC)

Interesting that the population density he gives ignores circle packing. Population should be 174,000. -- coyne -- 162.158.122.156 04:06, 28 March 2020 (UTC)

Circle packing is unimportant since he's just giving the population of this one circle. He's taking a radius of 6 foot around that person without specifying what he considers to be the radius of the person, but it can be inferred from the numbers:
from area: $\sqrt{145/\pi} \approx 6.8$,
from circumference: $43/(2\pi) \approx 6.8$,
from population density: $\sqrt{1/190000/\pi} \cdot 5280 \approx 6.8$,
so apparently he considers a person to have a radius of 0.8 ft, or about 0.5 m diameter, which seems reasonable. Zmatt (talk) 05:11, 28 March 2020 (UTC)

Possibly a play on the fact that horses are measured in hands? --orbitalbuzzsaw--
